Echinacea extract can have an immunostimulatory effect, as the inulin it contains can increase the number of granulocytes and white blood cells, enabling them to function effectively. It can also enhance the medicinal properties of eggshell cells, providing a bacteriolytic effect. The polysaccharides present in the extract can stimulate immune function and increase the phagocytic capacity of macrophages. Additionally, Echinacea can produce interferon and promote lymphocyte secretion.
